Samsung Range Error Code Over Temperature

Over temperature error

Samsung codesSamsung range codes

Over temperature error - top sensor temperature rises very high, estimated ceramic glass surface temperature exceeds 250°C (e.g., operating with empty cookware).

First step from the service manual

Allow hob to cool. Check if induction was operated with empty cookware. Check top sensor wire connection by burner position. Measure top sensor resistance for open circuit.

What Over Temperature means on a Samsung range

The Over Temperature error on a Samsung induction range activates when the top sensor detects that the ceramic glass surface temperature has reached or is approaching 250°C. This threshold represents a critical safety limit. The induction hob continuously monitors thermal conditions through a sensor positioned beneath the ceramic glass near each burner. When that sensor registers a temperature spike that corresponds to an estimated glass surface temperature exceeding 250°C, the control board triggers this fault and shuts down the affected burner zone to prevent damage to the glass, the underlying components, and any cookware or food involved.

The most frequent cause of this fault is operating the induction hob with empty cookware. Induction heating transfers energy directly to ferromagnetic cookware. Without food or liquid in the pan to absorb and distribute that heat, temperatures rise very rapidly and can exceed safe limits within minutes. The top sensor detects this thermal spike and responds accordingly. Other causes include a failed or disconnected top sensor that is sending incorrect resistance readings to the control board, leading to a false over-temperature reading even under normal cooking conditions.

Diagnosing this fault correctly requires confirming the operating conditions at the time of the error, inspecting the top sensor wire harness connection at the burner position for looseness or damage, and measuring the top sensor resistance with a multimeter to rule out an open circuit. A properly functioning sensor will show a consistent resistance value. An open circuit reading indicates sensor failure and replacement is necessary. If the sensor and wiring check out, the control board itself may be interpreting sensor data incorrectly.

Common causes of Over Temperature

  1. 01

    Empty cookware on active burner

    Wiring / connection

    Running the induction burner with an empty pot or pan causes rapid, uncontrolled temperature rise because there is no food or liquid to absorb the heat. This is the most common trigger for this fault and leaves no permanent damage if caught quickly.

  2. 02

    Disconnected top sensor wire

    Wiring / connection

    The wire harness connecting the top sensor to the control board can loosen over time or from vibration. A loose or disconnected connector can cause erratic or falsely high temperature readings, triggering the over-temperature fault even during normal cooking.

  3. 03

    Failed top sensor (open circuit)

    Part replacement

    If the top sensor itself has failed internally, a multimeter check will show an open circuit instead of a valid resistance reading. A failed sensor will misreport temperatures to the control board and must be replaced to restore normal operation.

  4. 04

    Oversized or incompatible cookware

    Wiring / connection

    Using cookware that extends significantly beyond the burner zone can concentrate heat unevenly near the sensor location. This can cause localized surface temperatures to spike and trigger the over-temperature threshold even with food in the pan.

  5. 05

    Control board fault

    Part replacement

    If the top sensor and all wiring connections test correctly, the main control board may be misreading or misprocessing the sensor input and generating a false over-temperature error. Control board replacement is a last-resort diagnosis.

Frequently asked questions about Over Temperature

What does Over Temperature mean on a Samsung range?
The Over Temperature error means the top sensor beneath the ceramic glass detected that the estimated surface temperature exceeded 250°C, which is above the safe operating limit. The range automatically shuts down the affected burner zone to protect the glass and internal components. This most commonly happens when the induction burner is used with empty cookware. The fault can also appear if the top sensor or its wiring has failed.
Can I fix the Over Temperature error myself?
In many cases, yes. If the error was triggered by running an empty pan, simply allow the cooktop to cool completely, then restart. If the error persists, inspect the top sensor wire connection at the burner position for looseness or corrosion. You can also measure the top sensor resistance with a multimeter to check for an open circuit. Sensor replacement is a straightforward repair for technicians comfortable working with disassembled appliances, but a failed control board is more complex and may warrant a service call.
Is the Over Temperature error dangerous?
The error itself is a safety feature, not a danger sign. The range is doing its job by shutting down before temperatures can cause damage to the ceramic glass or surrounding components. However, the condition that triggered it, such as an extremely overheated empty pan, does pose a burn and fire risk if ignored. Never leave an active induction burner unattended, especially with empty cookware.
Will resetting the Samsung range clear the Over Temperature error?
Allowing the hob to cool fully and then powering the unit back on will often clear the fault if empty cookware was the cause. However, if the underlying cause is a failed top sensor or a wiring issue, the error will return during the next cooking cycle. Address the root cause before assuming a reset has resolved the problem.
How much does it cost to repair an Over Temperature error on a Samsung range?
If the fix is simply allowing the unit to cool and correcting cooking habits, there is no cost involved. Replacing a faulty top sensor is generally an affordable repair, with parts typically ranging from $15 to $60 depending on the specific model and supplier. A control board replacement is significantly more expensive, often ranging from $150 to $400 or more for parts alone, plus labor if a technician performs the work.
